Economic Benefit Improvisation based Optimal Placement and Sizing of Distribution Generation

The economy of the distribution system (DS) greatly depends upon the amount of electricity purchase from transmission grid and the line loss of the distribution system. The inclusion of distributive generation in the passive distribution system acts as an active power supply to the local load and thereby reducing the line loss and also reduces the amount of electricity purchase from the transmission grid. Reduced purchase of electricity from the grid helps to increase net savings of the distributive system and also increases the load utilization level of the power system network. Considering the above theme, in this paper maximization of economic benefit in terms of improving the net savings or net profit of the vertically integrated distribution system has been proposed. The maximum economic benefit optimization is carried through the stochastic optimization tools such as Real coded Genetic Algorithm (RGA) and Real coded Particle Swarm optimization (RPSO). The effectiveness of the proposed optimization has been tested with the two standard test systems such as 33 Bus and 69 Bus distribution systems. To attain the realistic results time varying load scenario has been incorporated and the results are recorded.
